Peter Harwood, Acas Chief Conciliator, says:
"Today at Acas, BAA met with Unite, Prospect and PCS trade unions. Acas has been shuttling between the parties and the process has been a challenging one, but we are pleased to report that a basis for settlement has been agreed.
As you would expect the details of the deal are confidential until the parties report back to their respective constituencies. We understand that this process should be completed by 1pm tomorrow after which details will be disclosed.
The unions will now be balloting their members on the proposed settlement with a recommendation that members vote to accept it.
Acas is pleased at this development and hope that the matter will soon be settled."
